  1. Mean coverage and consistency are calculated using the data amplified by the same WGA method according to Additional file 13: Table S7. HOMref, homozygotes where both alleles are identical to the reference; HOMmut, homozygotes where both alleles are different from the reference; HETref, heterozygotes where only one allele is identical to the reference. We formulate the mean counts of genotyped alleles of single cell sequencing sites that are consistent with ‘golden control’ at both alleles, at one allele, or that are inconsistent at both alleles as 2, 1, and 0, respectively
